2 Claims.

This invention relates to a steel bar and clinch nut adapted to be made therefrom.

It is particularly aimed to provide an exceedingly simple and strong bar from which clinch 5 nuts may be made of a shape to more readily penetrate openings in a sheet or the like, have portions to fill the openings, with the nut at eight faces having contact with the sheet and with the nut also having portions adapted to be clinched m against the sheet.

The more specific objects and advantages will become apparent from a consideration of the description following taken in connection with accompanying drawing illustrating an operative embodiment.

In said drawi'ng:-

Figure 1 is an end elevation of the bar stock;

Figure 2 is a side elevation thereof;

Figure 3 is an end elevation of a nut made from the said bar stock;

Figure 4 is a view made from the said bar stock taken at a right angle to Figure 3;

Figure 5 is a plan view of the nut;

Figure 6 is a vertical sectional view taken on the line 66 of Figure 5; Figure 7 is a view illustrating a pair of the nuts engaged with a sheet, preparatory to being clinched thereto, and

Figure 8 is a section showing one of the nuts clinched to the sheet.

Referring specifically to the drawing wherein like reference characters designate like or similar parts and first the Figures 1 and 2, a steel bar is shown at I0 having a pair of longitudinal ribs II rising therefrom and symmetrically with respect to the center and the side edges. Said ribs are inset from the said edges and extend from surfaces or planes I2 on the outside thereof while the metal between the ribs is thicker and extends above said plane I2 as at I3. faces of the ribs are inclined as at I4 while the outer surfaces I5 are also inclined but preferably better entry into an opening.

The inner sur- I2 continuous about the same. It will be understood that the nut is machined to provide such planar surface I2. adjacent the ends of the ribs here designated II' and it will be further noted that the ends of such ribs are inclined or bevelled as at H, preferably on the same angle as the outer surfaces I5 of the stock. A central opening is provided through the nut as at I8, having screw threads I9 therein, for engagement with the screw threads on bolt shanks.

The nuts may be used in plurality as disclosed in Figure 7, having the ribs I I and the raised portions I6 extending through openings I9 in a 15 sheet or plate 20, the raised portions I6 snugly fitting the openings I9 whereby eight surfaces of the nuts and plate 20 are in contact. Preferably the raised portion I6 is of the same height as the sheet or plate 20 as shown in Figure 7 and 8 and the ribs I I are adapted to be clinched over the adjacent edges of the sheet or plate as shown in Figure 8, the clinching of the ribs or prongs II' being effected, in a punch press, for example;

Various changes may be resorted to provided they fall within the spirit and scope of the invenvtion.

I claim as my invention:--- I 1. A one-piece nut of the class described having a body, a raised portion spaced from all sides thereof, two spaced elongated prongs extending from said raised portion in parallelism at opposite sides thereof and adapted to be clinched over an engaged element, said prongs having their outer ends and outer side surfaces bevelled for 2. A one-piece nut of the class described having a body, a raised portion spaced from all sides thereof, two spaced elongated prongs extending from said raised portion in parallelism at opposite sides thereof and adapted to be clinched over an engaged element, said prongs having their outer ends and outer side surfaces bevelled for better entry into an opening, and the inner surfaces of said prongs being bevelled.
